Borderlands Cheats

Hint: Early Eridian Weapon

One character must be a Siren.

Go back to Fyrestone in the Arid Badlands; and after you kill the Mothrakk a Eridian weapon will fall out but you have to search everywhere as the trash plot can be huge. When the Mothrakk is low on points shoot warning shots to get it to come towards you, then kill it on the approach.

Berserker: Eridian Cannon

Soldier: Thunder Storm
Siren: Ball Blaster or Wave Blaster

Hint: Rider Sniper Rifle

In New Haven there there are two hidden chests. When you recieve the quest to enter Trash Coast, head to New Haven. Head toward the blue shack (below the area where the repair kit is). Stand near the door and it will open. Ride the elevator down and to the basement. Defeat the Psychos and open the red chest to find the Rider. Rider is a unique sniper rifle manufactured by Gearbox, the maker of Borderlands. This weapon, along with other details in the room (a trash pile Christmas tree and a grisly leg lamp) are references to the movie "A Christmas Story."

Hint: Sucker Born Every Minute Achievement/Trophy

The description for the Sucker Born Every Minute Achievement/Trophy says "Paid for a worthless tour of the world's largest bullet." Go go the huge bullet and there should be a building closest to the bullet. There will be arrows pointing to a box with a $ sign on it. Simply activate the prompt here to get the Achievement/Trophy.

Item Duplication

Not %100 sure if this can be done splitscreen as I don't play it :/ but here's what you do.

In a co-op online game, preferably with friends, get the person holding the items that you want to duplicate to drop them on the floor and leave the game by exiting straight to the dashboard. Make sure the person who dropped the loot doesn't pass a save point! Just drop the loot and go to the dash'.

That person will not have lost a single item (if done right) and doesn't have to re-join the match or anything to have it work.

No more fighting over the best loot anymore
